Sonya was a flight attendant for Oceanic Airlines, and was aboard Oceanic Flight 815. She was in a relationship with Oceanic IT Technician Sam Thomas for nearly eight years. Sam possesses an engagement ring, which was purchased to propose to Sonya on the eight anniversary of their meeting.
It is unknown whether or not Sonya survived the crash, as she has yet to appear on the island. Sam has yet to give up hope, even though Oceanic Airlines has deemed the search a failure and prepared to name the passengers as deceased. Sam was contacted by someone from the Maxwell Group who claims that they knew Sonya, and within the picture were several clues, leading Sam on his way.
